Is this statement true or false? according to the 2008 national institute of child health and human development (nichd) nomenclature, there are four categories of fetal heart rate variability: absent, minimal, moderate, and marked.

Option-(True):

There are four categories of fetal heart rate variability or changes(As the variability in heart rate lasts for 10 minutes, either it will increase or decrease): absent, minimal, moderate, and marked.

Explanation:

Baseline Variability:

The analyses of the heart beat rate is done upon the consideration of two consecutive cycles of the heart beating. As the 2 cycles are measured with comparison of the data with the standards present.

As the fluctuations or variability inside the heart rate is analysed on the basis of the the "Amplitude range" of the signal generated from the heart pulses or beats(Amplitude is defined as the "distance" of the signals vertical point from that of its points near its initiation or origin.)

As there are four cases on basis of which the heart beat or pulses are analyzed, these four cases are as follows:Absent variability: During the absent variability the range of the amplitude range is found undetected.Minimal variability:When the heart beat is less then 5 beats per minute(BPM) inside the heart, and the amplitude range is found at its minimal range or value.Moderate variability: The pulses recorded or which are under consideration are between 6 and 25 beats per second(BPM), as the value is considerate normal and it comes in the healthy range for any child to have.Marked variability:The severe case occurs relating patients heart beat or pulses, when it gets more then 25 beats per minute. As it occurs when the person is facing some nutritional deficiencies or any other abnormalities in the heart's physical or functional form which generates more beats then normal.

The answer is reflection.
